Thanks! We are going to try and borrow my Dad's Wii (they aren't using it) just to play with it a bit.
DD needs to be active plus work on balance and core strength, which have been areas of weakness for her. Trying to get her to stop falling and need something fun to reinforce PT (so far, fun does not include momma making a hopscotch course out of blue painter tape in the hallway, sigh).
I'm really leaning toward Kinect.
